I am a heating engineer. They are so unreliable and have ridiculous parts prices. Bags of poorly designed poor quality rubbish. You have been warned. Just been to a fit a pump to glow worm ultracom, normal cost for pump £100 ish with 20 minute change time. This one £150 for pump and two half hours because isolation valves are cheap and stuck so had to do a full drain down . Absolute garbage.
